Re: 5 volts to the cold start valve

The cold start valve is powered by the thermo time switch. There is a new replacement that is electronic that people are having problems with, although the old ones seemed pretty reliable. Simplistically the path is ignition switch start, to TT switch, thru it to the CSV. After several seconds, the...

5 volts to the cold start valve

Finally started to dig into an inoperable cold start valve and found it’s only getting about 5 volts while cranking. The valve tests fine, I believe it needs somewhere around battery voltage to work. Checking here if someone has run into this with a known fix or further diagnostic. Thanks!

Re: Steering and Suspension Update

“HD/Sport” describes both B6 and B8 struts. The Bilstein part number on the box is the best way to identify the version. It’s very likely you have B6’s.

Re: Air Conditioning Diagram/Supplement?

I also recommend “Just needs a recharge” by the Hack Mechanic. Gives a good perspective on using modern ac components in vintage systems.

Re: Brake Servo Unit...Booster

Or is it motor oil that somehow finds it's way into the booster? I replaced the master cylinder at 195k and found about an ounce of what seemed like engine oil in the booster canister. I think that over time the 1 way valve in the vacuum hose to the booster had deteriorated allowing booster vacuum ...

Re: HELP: Speedo Cable Mystery

Anyone tried using a universal cable and bypassing the O2 sensor box? Personally I don't need a reminder every 30k to replace and oxygen sensor.

Re: Suspension Upgrade

The spring is contained by upper and lower perches on both the rear shock and front strut. A very short spring could rotate and lose its orientation under full extension, but unless something breaks, the spring remains secure in the assembly. I have H&R springs front and back. They both require a sm...

Re: Suspension Upgrade

Yes, Bilstein said the B6’s are fine with lowering springs. The early ones use a different strut according to the part numbers. I think the porpoising effect is slightly magnified by the seat construction with springs vs. foam but I’ve never driven one with a more modern seat with all foam seat cush...

Re: Different shocks for front and rear

I think the primary concern should be the age difference of the shocks vs. the brand difference. Bilsteins are available for the e12 in B6 or B8 for the rears, fronts B6 only. B6's are called Sports and B8's are Heavy Duty. B8's were traditionally recommended with lowering springs however I had a co...

Re: Turbo E12

Vintage turbo kits for e12s occasionally pop up but they're generally either incomplete and/or need rebuilding. I know the appeal of a turbo kit is bolt on performance but it's more than just adding the plumbing if you want a motor that stays together. Compression ratio (different pistons), methanol...

Re: Verify color of FRONT FOG LAMP switch

My 79 is orange and it lights orange. Not surprised the one you found is a different color, it's likely because of a different supplier today than 40 years ago. Interestingly, original hazard switches say "Hazard" but new replacements have the international triangle symbol for hazard. Don't throw ou...

Mike - here's a 10 year old post in the e28 forum with some comments from you that may help: https://www.mye28.com/viewtopic.php?t=98476 It's interesting to compare electronics failures in early BMWs that are starting to pop up to the same thing happening in the Porsche world.

Re: Question: Need a Rear Muffler Source

They're still available new from BMW. Not cheap, but if you want original... Billy Boat makes an exhaust system for early e24s that fits. SuperSprint makes one specific to the e12. Either system will run about $1k plus installation. There's just not enough of these cars on the road for the aftermark...

Re: Removing and remounting the "528i" metal letters on the trunk

I thought the "528i" badge was secured only by double sided tape...? In which case using fishing line in a sawing motion has always worked for me.
